RTS-08's (front lift) normally carried the same body codes as RTS-06's, but a few did get their own codes.

Quickly, though,model number assigning became extremely sloppy, apparently because the person assigned the task did not comprehend the system. "Hydrid" designations started to appear, like "T802WFD". A couple of batches of 30-foot buses were designated "RTS3062" and "RTS3066", with RTS30 meaning "RTS 30 foot" A couple of 30-foot batches were designated "T60206" in the original system.

By 1992, another simplified variant of the original system started to appear:

By 2000, the model designation system had now gone completely to pot. Designations such as "62VW" appeared (6 section, 102 inch, V-drive, wide front door). Variations included "T82VW" with an extra "T" prefix, "RT76VN" with an extra "RT", "802VN" with with designated by "02" instead of simply "2" . Some had the order reversed, such as "VN82". A few late ones had the last letters reversed even, such as "RT82NV". Also appearing were designations like RT86 (RTS, 8 panel, 96 inch) or RTS72 (RTS, 7 panel, 102 inch), or RT802 (RTS, 8 panel, 102 inch)

By 2001, anarchy ruled, and simple descriptions like "40x102" and "35x102" started appearing, as apparently the model number scheme had now bcome incomprehensible to the person responsible for assigning them.
